Digital Ice Technology

How cool is Digital ICE technology?

Old film and slides are often covered with dust and scratches. Epson scanners are able to remove these defects during scanning with Digital ICE technology.

Digital ICE technology uses infrared light, which is able to detect dust, hairs, finger prints or scratches. As infrared light is invisible it cannot reproduce the colour information of the photo and therefore only delivers the defect information to the scanner software.

So how does the technology work?

The photo is illuminated by the cold light lamp and the colour information of the image is captured and delivered to the scanner software. The photo is illuminated by the infrared lamp and only the defect information is captured and delivered to the scanner software. The two images (colour information and defects) are compared and the defects are removed by means of algorithms. The result is an image without defects.
